摘要，建筑能耗是能源消耗的主要构成部分之一，随着经济的发展社会的能源 问题及环境问题日益凸显。是以地下水源热泵系统做为一种经济环保的新技术应运而 生。80 年代来地下水源热泵系统发展极快、使用普遍，然则很多项目的应用缺乏对 所在地区的水文地质条件及应用性进行分析。为此本课题针对西安市渭河边某办公楼 进行详细的水文地质评价分析并进行与传统方案的经济性对比评价，将理论与实践相 结合以便于更好的指导地下水源热泵系统更广泛的应用。 首先，本文从几种热泵系统的工作原理及优缺点进行对比分析，分析确定每种 系统的适用条件。针对本项目的水文地质及场地的相关资料应用层次分析法建立地下 水源热泵系统和土壤源热泵系统的评价体系模型并计算二者的适宜性指数，得出两种 系统均适宜项目所在区域。 然后，综合分析两种系统的经济性、环境影响及地下水源热泵的回灌方式，并 着重分析了地下水源热泵的回灌形式，（1）部分回灌水通过回灌进回灌，其余部分 回灌水送入鱼塘补水减轻回灌压井的回灌压力；（2）回灌水直接排入渭河河道进行 自然沉降回灌；（3）全部回灌水通过回灌井回灌。比较确定地下水源热泵系统方案， 回灌方式采用部分回灌水通过回灌进回灌，其余部分回灌水送入鱼塘补水。 最后，根据设计的地下水源热泵系统方案利用 DEST 软件模拟结合负荷频率法计 算年运行能耗利用概算指标计算初投资并与传统系统进行对比。得出本工程地下水源 热泵系统的费用年值比采用冷水机组+燃煤锅炉方案的节省 18％。 本课题的研究对于地下水源热泵系统的设计及方案的选择具有很好的借鉴意义。 图 31 幅，表 40 个，参考文献 60 篇。 关键词，地下水源热泵系统；层次分析法；负荷特性；负荷频率法；经济性分析； 费用年值 中图分类号，TK519III Feasibility Study and Energy ConsumptionAnalysis of Water Source Heat Pump in an Office Building by the Weihe River Abstract: With the development of society, energy and environmental problems are becoming more and more prominent. Building energy consumption has become an important part of energy consumption in China. Therefore, groundwater heat pump has emerged as a green energy-saving air conditioning technology. In recent years, groundwater source heat pump system has developed rapidly and widely used, but the application of many projects lack of analysis of the hydrogeological conditions and applicability of the region. To this end, this project aims at a detailed analysis of hydrogeological evaluation of an office building on the Weihe River in Xi'an, and compares the economic analysis with the traditional scheme. Combining theoretical analysis and practice to better guide the promotion of groundwater source heat pump system application. Firstly, the working principle of the heat pump system and the advantages and disadvantages of several comparative analysis, analysis to determine the applicable conditions for each system. According to the hydrogeological and site conditions of this project, the suitability evaluation model of groundwater source heat pump system and ground source heat pump system is established byAHP. Then, combining the two systems recharge mode economy, environmental impact analysis and groundwater source heat pump, we analyze the three ways recharge groundwater source heat pump (1) Put the part of the back of irrigation recharge coming down through the back rest (2) The recharge water is drained directly into the Weihe River to carry out natural subsidence recharge; (3) All the recharge water is recharged through the recharge well. Comparison of groundwater source heat pump system to determine the program, using some recharge water recharge by recharging into the recharge, the rest of the recharge water into the pond into the water. Finally, according to the designed groundwater source heat pump system, the initial investment is calculated by using the DEST software to simulate the annual energy consumption calculation by using the load frequency method and compared with the traditional system scheme economically. The annual cost of groundwater source heat pump system is 18% less than that of chiller unit and coal boiler. The research of this topic has a good reference for the design of underground water source heat pump system and its applicability and economic evaluation. 31 Figures,40tables, 60references.
